Hall Effect Tester - High and Low Temperature Magnetic Field Type Thermometer, system software. The JH10 effector specially developed for this instrument system integrates a constant current source, a six-and-a-half-digit microvoltmeter and a complex switching relay-switch for Hall measurement, which greatly simplifies the connection and operation of the experiment.
Product Description:
The instrument system consists of: electromagnet, electromagnet power supply, high precision constant current source high precision voltmeter, Gauss meter, Hall effect sample holder, standard sample, high and low temperature Dewar, temperature controller, system software. The JH10 effect meter specially developed for this instrument system integrates a constant current source, a six-and-a-half-digit microvoltmeter and a complex switching relay-switch for Hall measurement, which greatly simplifies the connection and operation of the experiment. JH10 can be used alone as a constant current source and a microvoltmeter. It is used to measure important parameters such as carrier concentration, mobility, resistivity, and Hall coefficient of semiconductor materials. These parameters must be controlled in advance to understand the electrical properties of semiconductor materials. Therefore, the Hall effect test system is to understand and study semiconductor devices. It is a must-have tool for the electrical properties of semiconductor materials. The experimental results are automatically calculated by the software, and the Bulk Carrier oncentration, Sheet Carrier Concentration, Mobility, Resistivity, and Hall coefficients can be obtained at the same time. Coefficient), magnetoresistance (Magnetoresistance) and so on.
